Thread: simple c program

plz help to solve the simple c program,

Code:

#include <stdlib.h>

int main()
{
   float cp,sp,p,l;
   printf("Enter cost Price and selling Price:");
   scanf("%f%f",&cp,&sp");
   p=sp-cp;
   l=cp-sp;


   if (p>0)
       printf("The seller has made a profit of Rs.%f",p);


   if (l>0)
        printf("The seller has made a loss of Rs.%f",l);


    if (p==0)
        printf("There is no loss no profit");


    return 0;
}

where cp= cost price , sp= selling price , l= loss , p = profit ,,

In the future, you need to explain what your problem is. Does the code compile? Is there an error or warning message you can't fix? Copy-paste the error message(s) exactly so we can help. If the program compiles, does it crash when you run it? Do you get no output? Do you get the wrong output? Tell us the input you provided, the output you expect and the output you actually get.

In this case, you have a simple syntax error:

Code:

$ gcc -Wall -g -std=c99  sale.c   -o sale
sale.c: In function ‘main’:
sale.c:6: warning: implicit declaration of function ‘printf’
sale.c:6: warning: incompatible implicit declaration of built-in function ‘printf’
sale.c:7: warning: implicit declaration of function ‘scanf’
sale.c:7: warning: incompatible implicit declaration of built-in function ‘scanf’
sale.c:7:25: warning: missing terminating " character
sale.c:7: error: missing terminating " character
sale.c:8: error: expected ‘)’ before ‘p’
sale.c:25: error: expected ‘;’ before ‘}’ token
sale.c:5: warning: unused variable ‘l’
sale.c:5: warning: unused variable ‘p’
make: *** [sale] Error 1

1. The "implicit declaration" messages mean you need to #include <stdio.h>.
2. The "missing termination" message means you have an erroneous " floating around on line 7. Remove it. This error would be much easier to see if you had an editor with syntax highlighting. There are dozens of free ones available, so look into it. It's a simple but highly effective tool.

thank you , next time I will do it

now its fine , it was syntax error,
in the 7th line,
